M. Hujslová M. H. 158 (paratype PRA -22497 dried culture on MLA, culture CCF 3787 = CBS 153584) .</p><p>Habitat and geographical distribution.</p><p>Halomyrma pluriseptata was isolated from slightly saline inland soils (pH 6.8–7.2) in Czechia. According to GlobalFungi, H. pluriseptata has a broad geographical distribution, spanning from tropical to temperate climatic zones. Identical ITS sequences were found in 71 samples from aquatic and terrestrial habitats. Among aquatic biomes, H. pluriseptata was identified in marine salt marsh sediments in the UK (Alzarhani et al. 2019) and Massachusetts, USA (Lynum et al. 2020), as well as in marine sediments and roots of the seagrass Zostera marina in Croatia and Alaska, USA (Ettinger et al. 2021). Additional marine records include occurrences in the neritic benthic zone in Sweden (Retter et al. 2019). In freshwater environments, the fungus was found in lake sediments in China (Zhang et al. 2021) and in Potamogeton sp. roots in California, USA (Ettinger et al. 2021). A notable occurrence was also recorded in the rhizosphere soil in a hypersaline lake in China (Luo et al. 2021), suggesting its adaptability to high-salinity freshwater systems. In contrast, H. pluriseptata was less frequently recorded in terrestrial biomes. It was identified in grassland soils in the UK (George et al. 2019) and Denmark (Frøslev et al. 2019), as well as coastal dune soils within wetland ecosystems in Canada (Roy-Bolduc et al. 2015). Further occurrences include sediments from a shrubland biome in California, USA (Lin et al. 2021), and soil samples from cropland fields in China (Zhao et al. 2018) and the Netherlands (van Rijssel et al. 2022). In other anthropogenic environments, the fungus was detected in plantation rhizosphere soil in China (Huang et al. 2020) and topsoil in Poland (Okrasińska et al. 2022), indicating its ability to persist in disturbed habitats.</p><p>Notes.</p><p>Hujslová et al. (2010) documented four strains of Lulwoana sp. (CCF 3787, CCF 3788, M. H. 585, and M. H. 630) from saline soils. However, a BLASTn search of their published sequences indicated that strain M. H. 585 (GenBank accession FJ 430720) is affiliated with the Magnaporthaceae, while the other three isolates have affinity with the Lulworthiales . Consequently, two strains, CCF 3787 and CCF 3788, were included in our study and are now recognised as H. pluriseptata, while strain M. H. 630 was unavailable for examination.</p><p>The cultural characteristics and description of H. pluriseptata are based on the ex-type strain CCF 3788. While both strains shared identical ITS, LSU, and SSU rDNA sequences and exhibited comparable conidial morphology, they displayed differences in cultural characteristics. The non-type strain CCF 3787 demonstrated slightly faster growth on MLA, OA, and PCA (i. e. 50–52 mm in diam. on CMD, 44–46 mm on MLA, 62–64 mm on OA, 48–55 mm on PCA, and 24–25 mm on PCASW) within the same incubation period. Additionally, the ex-type strain CCF 3788 produced pigments that diffused into the agar: golden-yellow on OA and yellow on PCA and PCASW, whereas CCF 3787 did not exhibit pigment production on any tested medium.</p><p>Additionally, PDA and PDA supplemented with NaCl were used to further assess the growth and salt tolerance of H. pluriseptata (CCF 3788) under in vitro conditions. Colony morphology on PDA was comparable to that observed on CMD, MLA, OA, PCA, and PCASW, exhibiting abundant aerial mycelium and reaching 40–52 mm diam. in 2 wk. In contrast, growth on PDA with added NaCl was significantly reduced, with colonies reaching only 6–9 mm in diam. in 2 wk. Hujslová et al. (2010) examined the effects of pH and salinity on the growth of CCF 3787 and CCF 3788 using soil agar supplemented with rose Bengal and glucose.</p><p>The multicellular brown conidia of Halomyrma resemble those of Moromyces (Abdel-Wahab et al. 2010), a genus that currently includes a single species, M. varius .</p></div>	https://treatment.plazi.org/id/DD5A3811BEC35E2183305CBA468F6DF6	Public Domain	No known copyright restrictions apply.

The texture varied from mucoid to waxy, cobwebby at the centre and on the inoculation block, surface initially rugose, becoming cerebriform, and gradually developing deep radial furrows and cracks. Colonies were cream-coloured to yellow-beige, later exhibiting a deep purple pigment diffusing into the agar at the centre and margin, as well as forming irregular spots, often distinctly zonate.

On PCASW colonies 70–98 mm diam. in 2 wk. Colonies were initially composed of submerged mycelium, formed by sparse white vegetative hyphae visible only in translucent light (1 wk); later, hyphae became denser and subhyaline (2 wk) and gradually darkly pigmented (3 wk). In 8 wk, colonies were circular, flat, margin rhizoidal, dark brown, whitish grey at the centre, dark grey to almost black towards the margin; the texture ranged from cottony to sparsely floccose at the centre, cobwebby towards the margins, occasionally exhibiting zonation with alternating zones of sparse and dense growth, conspicuous submerged growth, with numerous colourless exudates on aerial hyphae, reverse none.

On PCASW, mycelium composed of hyphae 2–4 μm wide, cylindrical, septate, branched, hyaline at first, becoming subhyaline to brown; hyphae often slightly swollen, 5–7.5 μm wide, or monilioid. Monilioid hyphae develop either terminally or laterally, solitary or in clusters, which appear on the surface of colonies or immersed in agar.

The monilioid hyphae elongate on the terminal end; cells mature gradually, starting as hyaline and becoming dark brown to dark olivaceous brown with age, collapsing in old cultures (ca. 3 mo old). Sterile, globose structures developed at margin of the colonies; they are composed of dark brown, pseudoparenchymatous cells surrounded by sterile brown hyphae. On MLA, mycelium composed of hyphae 2–3 μm wide, cylindrical, septate, branched, hyaline, becoming dark brown in old cultures (ca. 4–6 mo old); hyphae often swollen, 3.5–5 μm wide, or monilioid.

All dried cultures are on PCASW.</p><p>Habitat and geographical distribution.</p><p>The species is known as a root mycobiont of the seagrass Thalassodendron ciliatum in Mauritius. No samples with identical sequences have been recorded in the GlobalFungi database.</p><p>Notes.</p><p>Clusters of dark monilioid hyphae composed of thick-walled, brown cells were only observed on PCASW (Fig. 7 A – G). The dark, spherical aggregations of hyphae forming compact structures embedded within the agar medium remained sterile and may represent early stages of ascomatal formation (Fig. 7 I). While monilioid hyphae were also present on MLA (Fig. 7 H) and PCA, they mostly appeared as composed of irregularly swollen cells that remained hyaline, becoming pigmented in old cultures. Such cells never formed clusters and were reduced in both shape and size compared to those formed on PCASW.</p><p>On PCASW, the fungus developed extensive, dark, effuse colonies characterised by distinct submerged growth, sparse mycelium, and monilioid hyphae. Similar colonies were observed on PDA with NaCl. In contrast, on MLA and PCA lacking seawater, growth was considerably slower, and colonies appeared more compact with densely interwoven hyphae, displaying a mucoid-waxy texture. On MLA, the fungus produced a deep purple pigment. Growth on PDA and PDA supplemented with NaCl varied among the strains of T. purpureus (CBS 153576, CBS 153577, CBS 153578), and in contrast to H. pluriseptata (CCF 3788), was generally more vigorous on the salt-amended medium. The ex-type strain CBS 153577 exhibited the most robust growth, forming colonies 43–45 mm in diam. on PDA with NaCl within 2 wk, while growth on PDA alone was considerably slower, with colonies reaching only 6–7 mm in the same period. Strains CBS 153576 and CBS 153578 showed little to no growth on either medium, with mycelium developing only around the inoculation block.</p><p>Thalassodendromyces purpureus was the only fungus isolated from the roots of T. ciliatum that were heavily colonised by DS hyphae. This fact, together with similar hyphal morphology observed in the host and in culture (see the “ Microscopic observations ” in the Results), strongly suggests that the isolated fungus described here represents the mycobiont forming the newly described root-fungus symbiosis in T. ciliatum . However, a resynthesis experiment is necessary to confirm this in accordance with Koch’s postulates and to clarify the nature of the symbiosis, i. e. to determine where it lies along the mutualism – parasitism continuum.</p></div>	https://treatment.plazi.org/id/AB180642B3CD506781740617B8CBB645	Public Domain	No known copyright restrictions apply.
